I've been running Bodhi 3.2.1 on a Chromebook for a while now (works like a charm). Recently I wanted to install some newer software so today I set myself to updating sources.list. At first it went ok (different mirror), but later I seem to have "broken" some things: a lot of icons in the start menu disappeared (the "Bodhi native" ones are still there), and I started to get error messages with Synaptic.

I put the original sources.list back, and got this message on starting Synaptic:

E: The value 'trusty-security' is invalid for APT::Default-Release as such a release is not available in the sources
E: _cache->open() failed, please report.

Is there a "latest" sources.list available for Bodhi that I should use?
